  • plants for the fermentation of solid biomass have essentially a generally gas-tight fermenter for receiving the solid biomass. This may be a garage or tunnel-shaped structure into which the biomass is introduced, for example in the form of a heap.
  • fermenters according to the prior art generally have a device for charging the biomass with a liquid medium.
  • the liquid medium is usually so-called percolate, which by the biomass, which is normally in the form of a Batch or as a debris and thus has a certain porosity, is passed.
  • the percolate is used in particular as a carrier for the anaerobic biology, which is responsible for the fermentation process and usually allows only the fermentation of solid biomass, which is wetted by the percolate and moistened with it.
  • the fermenters of the type in question usually have a gas outlet for the removal of biogas from the fermenter and a gas inlet for the supply of gases in the fermenter.
  • the gas outlet serves at least primarily to remove the biogas from the fermenter, while the gas inlet is usually used to rinse the fermenter, for example, to displace the oxygen from the fermenter with a carbon dioxide-containing gas to the transition from aerobic During the anaerobic phase, among other things, to reduce the risk of explosion by removing explosive gas mixtures or gases which can lead to the formation of such mixtures.
  • Such rinses which are made in particular when starting and stopping the fermenter and the associated switching between aerobic and anaerobic processes have the problem with it, that during rinsing a large amount of gas is formed with a no longer technically useful composition, which must be supplied to a disposal, for example, in special Fkelig or filter systems usually.
  • a considerable amount of biogas is lost in this way, making the process inefficient.
  • the invention has for its object to provide a plant for the production of biogas and a method for operating a plant for the production of biogas, which allow more efficient biogas production, in particular with regard to the prevention of gas losses by rinsing processes and a higher potential content of dry substrate.

  • the plant preferably has a delivery device for conveying the biogas in the direction of the gas inlet.
  • This conveyor may be, for example, a compressor or compressor which is capable of conveying the biogas in the direction of the fermenter.
